An Acres Per Hour (APH) calculator is a valuable tool used in agriculture and landscaping to estimate the amount of land that can be covered in an hour.
This calculator helps farmers, landscapers, and equipment operators determine their efficiency and productivity when performing tasks such as mowing, planting, or harvesting. By inputting variables like the width of the equipment and the speed of operation, users can quickly estimate how many acres they can cover in an hour.

Mowing Acres Per Hour Calculation Formula
The basic formula for calculating Acres Per Hour is:
APH = (W x S) / 99
Where:
- APH = Acres Per Hour
- W = Width of the equipment in feet
- S = Speed of operation in miles per hour
- 99 = A constant factor for unit conversion
This formula takes into account the width of the mower deck or other equipment and the speed at which it operates. The result gives an estimate of how many acres can be covered in one hour of continuous operation.
How do I calculate acres per hour?
To calculate acres per hour, follow these steps:
- Measure the width of your equipment in feet.
- Determine the speed at which you’ll be operating in miles per hour.
- Multiply the width by the speed.
- Divide the result by 99.
For example, if you’re using a 60-inch (5-foot) mower at a speed of 4 mph:
APH = (5 x 4) / 99 = 20 / 99 ≈ 0.20 acres per hour
How many acres an hour mowing?
The number of acres mowed per hour can vary significantly depending on several factors:
- Mower size: Larger mowers cover more area per pass.
- Operating speed: Faster speeds increase coverage but may reduce cut quality.
- Terrain: Flat, open areas allow for higher speeds than hilly or obstacle-filled landscapes.
- Operator skill: Experienced operators can work more efficiently.
As a general guideline:
- A residential push mower (21-inch deck) might cover 0.5-0.8 acres per hour.
- A riding mower (42-inch deck) could manage 1.5-2 acres per hour.
- A commercial zero-turn mower (60-inch deck) might handle 3-4 acres per hour under ideal conditions.
How do you calculate ha per hour?
To calculate hectares (ha) per hour, you can use a similar formula to the acres per hour calculation, with a slight modification:
Ha/hour = (W x S) / 120
Where:
- W = Width of the equipment in meters
- S = Speed of operation in kilometers per hour
- 120 = Conversion factor
For example, if you’re using a 3-meter wide seeder at 8 km/h:
Ha/hour = (3 x 8) / 120 = 24 / 120 = 0.2 hectares per hour
How many acres an hour with a 12 row planter?
To calculate the acres per hour for a 12-row planter, we need to consider the row spacing and operating speed. Let’s assume a common row spacing of 30 inches (2.5 feet) and an average planting speed of 5 mph:
- Calculate the total width: 12 rows x 2.5 feet = 30 feet wide
- Apply the APH formula: APH = (W x S) / 99 APH = (30 x 5) / 99 = 150 / 99 ≈ 1.52 acres per hour
A more realistic estimate might be 70-80% of the calculated value, resulting in approximately 1.1 to 1.2 acres per hour for a 12-row planter under typical conditions.
